US physician practices from the CMS NPPES register: fields, method and prices, nationwide or by state.
Dermatologist email list
The CMS NPPES register (file of 2026-09-14) lists ~16,000 registered practice addresses where at least one provider carries a dermatology code. That is about 3.3% of the ~483,000 physician addresses in the same file, and an upper bound, because the register keeps closed and duplicate addresses. The Bureau of Labor Statistics counts 11,370 dermatologist jobs (May 2025), a figure that leaves out self-employed dermatologists. The dermatologist list holds one row per dermatology office we can confirm, with its published email and the page where we found it. You can order it now, nationwide or by state.

In the public register
Rounded count in CMS NPPES, file of 2026-09-14. It is an upper bound: registers keep closed and duplicate entries, which our checks remove.
States plus DC with at least one entry in the register.

Who is included
An office is in this list when a provider registered at its address carries a dermatology taxonomy, any code starting 207N, in any of the 15 taxonomy slots of an NPPES record. That covers general dermatology and its subspecialties: Mohs micrographic surgery, dermatopathology, pediatric dermatology and procedural dermatology. It also covers dermatology groups registered as organizations under those codes. Medical spas and aesthetic clinics with no dermatologist registered are left out, and so are dermatology physician assistants and nurse practitioners who have no dermatologist at their address. Other specialties are in the physician email list.
In the register, ~20,000 individual dermatologists and ~9,100 organizations carry a dermatology code. One dermatologist can work at several offices of the same group, and one group can run dozens, so neither figure is an office count.
Physician email listRegistered dermatology addresses by state
California, Florida, New York and Texas hold the most registered dermatology addresses, and together they hold about 39% of the US total. Florida has about 60% of California's population but nearly four-fifths as many dermatology addresses. Wyoming, Vermont and North Dakota hold the fewest.

Where dermatology addresses cluster
The District of Columbia has the most dermatology addresses per resident, at 9.9 per 100,000, about twice the national rate of 4.7. Florida (6.9), New York (6.8) and Maryland (6.6) follow, then Connecticut and Massachusetts. Arkansas has the lowest rate, at 2.9, with Kentucky, Minnesota and Wyoming next. The ten highest rates, states and DC:
| State | Per 100,000 residents | In the public register |
|---|---|---|
| District of Columbia | 9.9 | ~70 |
| Florida | 6.9 | ~1,600 |
| New York | 6.8 | ~1,400 |
| Maryland | 6.6 | ~410 |
| Connecticut | 6.2 | ~230 |
| Massachusetts | 6.1 | ~440 |
| Hawaii | 5.8 | ~80 |
| Rhode Island | 5.7 | ~60 |
| Colorado | 5.4 | ~320 |
| California | 5.3 | ~2,100 |
Counts are rounded.
Texas ranks fourth by count but sits below the national rate per resident (3.8), as do Georgia and Tennessee.
Dermatology's share of each state's physician addresses
Nationally, dermatology addresses make up 3.3% of all registered physician addresses. The share varies from about 2.2% to 4.7% by state, and it doesn't follow the per-resident ranking:
- Highest shares: Wisconsin (4.7%), Utah (4.5%), Rhode Island (4.3%), Massachusetts (4.3%), Minnesota and North Dakota (both 4.25%).
- Lowest shares: Arkansas, Wyoming and Vermont (each about 2.2%), then Kentucky and New Mexico (both 2.4%).
- DC has the highest dermatology rate per resident but a share only a little above the national figure (3.8%), because it also has by far the most physician addresses per resident.
Minnesota and Wisconsin have few dermatology addresses per resident but a high share of their physician addresses. A likely reason is that large health systems there register many doctors at a few shared sites, which keeps the physician address count low. For a campaign aimed at dermatologists, a state's total physician count is a weak guide to its dermatology count. Shares are computed from the two register counts for each state, from the CMS file of 2026-09-14.

Where the data comes from
The list starts from the CMS National Plan and Provider Enumeration System (NPPES), the federal register of healthcare providers, file of 2026-09-14. We group MD and DO registrations by practice address, match each location to its own website or its group's location page, and record the emails and phone numbers published there, with the page URL. We check each email with the receiving mail server and leave out locations we can't confirm as current.

Questions about the dermatologist list
How many dermatologists are in the US?
BLS counted 11,370 dermatologist jobs in May 2025 (OEWS, SOC 29-1213). That is a floor, because it leaves out self-employed dermatologists. The CMS NPPES register holds ~20,000 individual dermatology registrations, an upper bound, because retired dermatologists keep their records and the count includes every subspecialty. The real number lies between the two. More on the doctor statistics page.
Can I buy the dermatologist list now?
Yes. Choose nationwide or up to 10 states in the order panel on this page. It costs $249 nationwide, and the panel shows the price of each state file. Delivered within 24 hours, usually much sooner. That includes the nationwide file.
Does the list include Mohs surgeons and dermatopathologists?
Yes, when they are registered under a dermatology code. The specialty column will show which subspecialty is registered at each office, so you can keep or drop Mohs surgery and dermatopathology practices.
Are dermatology groups owned by private equity included?
Yes. The group_affiliation column will name the group where public evidence shows one. A blank will mean we found no public link, not that the office is independent.
Will the list include medical spas?
Only when a dermatologist is registered at its address. Spas run by other physicians or by nurses are outside this list.
How are dermatologist files delivered and refunded?
The same as every list. Delivered within 24 hours, usually much sooner. Card held at checkout, charged on delivery. The 5% bounce refund applies too. See pricing.
